We study the confined states of a molecule formed by two laterally coupled quantum dots. The static electric field and incident plane wave laser field are considered
with different polarization. The respective Shr¨odinger equation is obtained in the framework of the high-frequency limit of Floquet theory. It is shown that the
electric field has a qualitative impact on the spatial symmetry of electronic states. An in-depth study of electric and laser field combined effects show a strong
correlation between them. Additionally, we show that the linear, nonlinear and total optical absorption coefficients and relative refractive index of the considered
structure can be effectively tuned by changing electric field strength and intense laser field parameter. Our results indicate the possibility of controlling the optical
response of double quantum dots molecule for future applications in nanostructure-based quantum information science.
